Ohh bullshyt.
If it were a 17 y/o male who was dealing drugs instead of a 17 y/o female dealing her body, you wouldn't have this level of sympathy.
You'd simply say his lifestyle caught up with him.
And that's what happened to her.
You make a good point, but the article with more detail explains that this wasn't her lifestyle...all allegedly, of course: Mr. Downey had struck out in trying to find another escort and called her Miss Burg's ex-boyfriend, who got paid $200, and told Burg that all she'd have to do was "party and keep the guy company."
What exactly went down in his place is unknown, and there's lots of evidence not released, I'm sure, but it's not like this girl (used because she's a minor) was a regular. And perhaps she did or did not expect to be paid for "services" doesn't matter--selling her body was not something to harm others like selling drugs can be. So I don't think they are comparable, and I also feel bad that Miss Burg's (or the hypotheical drug dealer's) background, upbringing, or character prevented her from acting dangerously.
